Predictors of vascular complications in octogenarians: multivariate analysis

Twenty-eight data elements selected for analysis

Predictors by univariate analysis:

femoral approach (p<0.001)

small size (p<0.005)

female gender (p<0.009)

thienopyridine treatment (p<0.09)

thrombolysis within 24 hours (p<0.015).

Predictors of the primary endpoint by multivariate analysis:

femoral approach OR: 22.2 95% CI: 2.4-207.9 p=0.007 thrombolysis w/in 24 h OR: 19.5 95% CI: 2.2-172 p=0.007

patient height <158 cm* OR: 6.4 95% CI: 2.0-20.4 p=0.02

11stst height quartile height quartile

Conclusion (1)

Combined end-point of all approach related vascular complications leading to prolonged hospital stay is significantly lower in Octogenarian randomized to Transradial approach for Coronary angiography and/or PCI compared to Transfemoral approach

Approach related vascular complications are more severe in Femoral randomized group and occur mainly in patients actually approached through Femoral artery (cross overs)

Per-protocol analysis shows a higher occurrence rate of the combined end-point and significant blood loss in procedures performed through Femoral artery and a trend for a lower transfusion rate

Conclusion (2)

As in younger patients, for coronary angiography, in intention-to-treat analysis, procedural and X-Ray exposure times are slightly but significantly longer in the Transradial group without differences in contrast medium and equipment use

As in youger patients, for PCI, there is no difference in Procedural and X-Ray exposure times, contrast medium volume and equipment use

Conclusion (3)

Transradial approach is an effective way to reduce the rate of vascular complications related to coronary angiography and PCI in the high risk octogenarian population
